Can Sonic outrun a disease that turns everyone into robotic zombies? The world has fallen to the Metal Virus, a manufactured plague that transforms all it infects into mechanized drones under Dr. Eggman's command. Even Sonic the Hedgehog has been infected, though his speed has allowed him to keep the virus at bay. Now, with the population more infected than not and the virus constantly spreading, Sonic and his friends in the Restoration launch a desperate plan!

When things go from bad to worse, Sonic and his friends find themselves on Angel Island, the last safe place, teaming up with their old foe Dr. Eggman, to defeat the Deadly Six and reclaim the Chaos Emeralds in a last-ditch effort to save everything.

Collects issues #21-32 and the 2020 Annual from volumes 6-8 (The Last Minute, All or Nothing, and Out of the Blue) of the Sonic the Hedgehog series.
